LOGGING APPARATUS.

Specification of Letters Patent.

Patented April 3, 1906.

To all whom it may concern:

Be it known that I, Josnrn BUTLER, a subject of the King of GreatBritain, and a resident of Naumai, New Zealand, have invented a new anduseful Improvement in Logging Apparatus, of which the following is aspecification.

My apparatus combines the advantages of a cone in the hauling of the logwith the advantages of a jacking apparatus, which lifts the end of thelog preliminarily to loading onto itself or for the purpose of clearingobstructions.

In the accompanying drawings, Figures 1 to 4, inclusive, arerespectively a plan, a side, a cross-section, and a front end View ofthe shoe portion of my apparatus in the simplest form in which I haveheretofore constructed it. Figs. 5, 6, and 7 are a plan, side, andcross-section of the shoe in an improved form. Fig. 8 represents myapparatus in the act of hauling a log. Fig. 9 represents the apparatusattached to the login end-on position and in the position that theapparatus occupies when in the act of starting and loading the end ofthe log onto itself. Figs. 10 and 11 are details.

1 is a shoe of sheet metal of sufficient stiffness to withstand all ofthe strains that it is called upon to bear-in the uses herein referredto. This shoe should be approximately of a width at least equal to thediameter of the log and of a length somewhat in excess of said diameter.This shoe in its simplest form, (shown in Figs. 1 to 4, inclusive,) issubstantially flat throughout, excepting at and near its forward end,where it is bent upward, as shown. At its forward end it is perforatedin the form shown. The enlarged portion 2 of the perforation or eye isadapted for the-free movement therethrough of the hauling-chain, whilethe reduced portion 3 of the perforation or eye acts as a stop to prevent the movement therethrough of the hauling-chain when required. Thisperforation being in the upwardly-bent portion of the shoe occupies theinclined position shown, so that a forward pull upon the chain has thetendency to disengage the chain from the lockin constricted portion 3and pull it forward through the unlocking enlarged portion 2, whereas astrain in the opposite direction has the contrary tendency.

4 and 5 constitute the dogs by which the end of the log is grappled andwhich are connected with the triangular link 6 by the chains 7 and 8,for which, of course, ropes are the equivalent.

9 is a hook engaging the triangular link 6 and connected by a swivel 10with the hauling-chain 11. The triangular link 6 is of the oblong formshown, so that when the dogs are secured to the sides of the log and thechains 7 and 8 are notched in the corners of the logs said chains may betightened by moving said link 6 from the crosswise position shown indetail in Fig. 10 to the length wise position shown in Fig. 11. Thelinks of the chain 11 are so constructed as to properly cploperate withthe perforations 2 3 of the s cc.

In the improved form shown in Figs. 5, 6, and 7 the shoe contains alongitudinal downward corrugation 12, (of which there may be one ormore,) extending from front to rear, more or less, which acts not merelyto stiffen the shoe itself, but also as a keel to steady its movements.The forward part of the shoe may be also upwardly rounded at its edges,so as to produce the form of ascoop, gradually dying into a flat surfaceapproximately midway of its length.

In operation for the purposes of loading the end of the log preparatoryto hauling the shoe will be stood up with a backward inclination infront of the log, providing it be endon, as shown in dotted lines inFig. 9, and the chains having been adjusted so as to be taut, thehauling-strain will cause the shoe, pivoting on its base, to first liftthe end of the log, as shown in full lines, and then drop it ontoitself. In dropping upon the shoe the log will commence its forwardmovement toward the engine, and thus will be overcome, with a minimum ofpower, the inertia of the log and the other obstacles which alwaysrender the starting of the log the most strenuous part of the operation.

The jacking ability of the apparatus will also come into play forcausing the end of the log to clear obstructions and also for loadingthe log onto the shoe when in a side-on position.

In the operation of the apparatus above described the tendency of thechain will be to haul the log up onto the shoe, which it is permitted todo by reason of the free passage in a forward direction, which isafforded for the chain by the large portion 2 of the perforation throughwhich it passes. Every advantage which the chain gains over the log inthis respect it retains, because the chain is looked against any returnmovement by the engagement of its links with the narrow portion 3 of theperforation.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. As an article of manufacture, a loggingapparatusshoe consisting of a log-bearing approximately flat body with anupwardlycurved forward extension having a perforation therein, a chainextending through the perforated portion, and a grappling device carriedby said chain.

2. As an article of manufacture, a loggingapparatus shoe consisting of alog-bearing corrugated flat body with an upwardly-curved forwardextension having a perforation therein, a chain passing through theperforation, a hook connected to the chain, log-gripping mechanism, anda connection betweent the hook and the log-gripping mechanism.

3. In a logging apparatus in combination a log-carrying shoe having anapproximately flat log-bearing body portion, and a forward extensiontherefrom, in combination with log-grappling mechanism formed of aplurality of hooks, a flexible mechanism between said hooks, and ahaulingchain passing through the shoe and. forming an adjustable lockingengagement with the forward portion of said shoe whereby the whole mayoperate as a acking device.

4. As a logging apparatus, in combination, a log-grappling device, anoblong link whereby the same may be tightened, a haulingchain and a shoecontaining a perforation through which said hauling-chain extends.

In testimony whereof I have hereunto signed my name in the presence oftwo subscribing witnesses.
